 C. horrida and C serratifoUa among the Colktice veras^ whilst 

 C obcordata and C Ephedra^ are put into the section (?) Re-

Brongniart's " Memoire sur la famille des Rha 

 peared in the lOth vol, of the Annales des Sciences Naturelles. 

 There, part of the character of Colktia runs, « Petala nulla 

 vel rainutissima, linearia," and " Discus brevis, cupulaeforniis, 

 fundo calycis adnatus : " and the species included are C. 

 ftorrida, serratifoUa, tetragona, a new species from Peru, and 

 C. pyhescenSi a New Holland one from my Herbarium, which 

 has a short tube, petals, and a disc of a very different charac- 

 ter from that of C. spinosa, to which is added, as a " species 

 affinis," C. infesta {Ceanothus infesta, Kunth and De Can- 

 dolle, which has petals and a disc lining the whole tube : 

 while Colletia obcordata and C. Ephedra, of Vent, are trans- 

 ferred to the new genus Betanilla. 



■■ In all the species now noticed, there is so strong a general 

 resemblance that it seems almost a pity to separate them 

 generically, and Brongniart, who has so done, has nevertheless 

 included into his Colletia species with and without petals, 



and 



If, 



therefore, Retanilla is to be removed from Colletia, by the 

 same rule C. pubescens and C. infesta ought to be : and, now 

 that we are acquainted with three other Colletia, from the 

 travels of Dr. Gillies, agreeing in every essential particular 

 with the generic character of C. horrida, I shall deem this 

 latter the type of the genus, which I would thus define :
